Bill Dunster claims his RuralZED house, which will be shown at the Ecobuild exhibition (26-28 February at Earls Court), meets the unprecedented (and non-existent – he invented the term) Level Seven of the Code for Sustainable Homes, with a wind turbine producing energy to make up for the embodied energy in the materials and construction of the structure.
While this may appear a gimmicky claim, Dunster says the project is all about myth-busting. ‘Anybody can build to Level Six,’ he says [witness the Sheppard Robson and PRP houses at BRE innovation park], ‘but the key is to keep it affordable’. The basic kit of parts for a RuralZED house costs £116,000. Dunster says a typical house can be built in a month; Ecobuild’s prototype will be assembled in thee days.
RuralZED is a box which can be wrapped with a variety of elevations and roofing configurations. Units can be grouped to form a terrace or stacked to form a multi-unit building. The house can accommodate upgrades of technologies such as a wood pellet burner and photovoltaics.
